FRANK KOBNER, F GALESBURG, ILLINOIS, ASSIGNOB TO WINSLOW BOILER 6:: EN- GINEERING COMPANY, OF CHICAGO, ILLINOIS, A (3OBPORATION OF ILLINOIS.

' LIQUID-FUEL BURNER.

Application filed February 11, 1921, Serial No. 444,094. Renewed March 10, 1924.

To all whom it may concern.

Be it known that I, FRANK Konunn, a citizen of the United States, residing at Galesburg, in th e county of Knox and 6 State of Illinois, have invented certain new and useful Improvements in Liquid-Fuel Burners, of which the following is a specification, reference being bad therein to the accompanying drawing.

The invention relates to liquid fuel burners, and consists in the matters hereinafter described and then pointed out in the claims.

In the accompanying drawing. which illustrates a practical embodiment of my invention, Fig. 1 is a plan view of the device with part of the top flange of the pot broken awa for convenience of illustration;

Fig. 2 is a view in side elevation with the ot in vertical section on the line 2-2 of ig. 1, and i Fig. 3 is a view of the pot in transverse vertical section on the line 3 3 of Fig. 1.

In the drawing the reference numeral indicates an airdurt connected at its intake end to an air-blower 11 of a type capable of delivering a sufilcientquantity of air to ensure perfect combustion. and with its outlet end connected tangentially with the fire-pot 12 which is provided with a suitable opening for this purpose. By this arrangement the air for supporting the combustion of the flame in the burner is delivered to the fire-pot in a tangential stream.

The fire-pot or combustion chamber 12 is of any suitable contour in plan section to conform to the design of the steam generator or boiler with which it is associated, and in the present instance it is substantially circular. Its bottom plate 13 is flat, and its walls 14 are vertical, being curved at their upper and lower portions to form a rounded connection with the bottom 13 and an inwardly projecting ledge 15 forming the flame-discharge opening at the top and which is more or less restricted and smaller in diameter than the cross-sectional area of the interior. The chamber 12 is provided interiorly with bafile or deflector plates 16, preferably arranged in a pair spaced apart onthe wall opposite to the air-in et. opening. Each plate 16 is secured to the inner wall of the chamber and extends approximately the height of the chamber and is spirally inclined from its top to bottom rearwardly or u in the general direction of the travel of the air current introduced through the tangential 2H1 inlet and an is roundcd or curved in cross-section so that its free edge extends .lorux-irdly in advance of its oth r rdgc tothe pot and bv which 11 is lo'olo-n up and splashed into the chamber: This plate is inclined from its rear toward the center of the chamber to throw the oil particles forward us well as laterally, and not only atomizcs the oil falling upon it but also deflccts and spreads the igniting: flame of a pilot l'lllIIlt'l' 19 which is located eneath it: and the plate is referably provided. with perforations whici allow the oil to drip through and further atomize it in contact with the flame. By this arrangrment the burner 19 ignites the fuel and starts the heating: Home in the pot, which continues to burn as long as the oil is supplied to it. The bottom 13 is provided with a drain opening 20 normally closed by a plug to draw oll any oil that may escape into the pot while the device is out of operation.

As the bafilrvphatcs are arranged with their upper-ends in advance. or toward the air inlet they lead downwardly to divert the inflowing supply of air downwardly toward the floor of the chamber and into the zone where the oil is broken up and splashed into the chamber by the distributinglate, and the concavity of the bathe-plates being on their windward side or toward the airinlet they present their concave faces to the inflowing air and turn the swirling or rotating currents back on themselves and toward the center of the chamber to fill its entire area with the fuel mixture and direct the currents into the central llamedischarge opening at the top of the chamber.

When the fuel oil enters the pot it is atomized more or less by the distributing plate 18 and is readily ignited by the pilot ame. it being understood that the blower is then operating to furnish the air necessary to ensure complete combustion of the oil. The air passes into the pot in a tangentit column, and mixes with and further atomizes the oil to form the combustible mixlme. which assumes a gyrating or swirling course aruund the pet and thebafile or rlellmrlur plates direct the moving bpcly 9f fuel ililXilll'l tuwm-(l-the central discharge polling where it l'oi'ms a (Blltl'fll column of Humeol' grunt intensity which fills and pro-..

jt'cts out, of the opening.

l claim:

1. In a liquid {iwl burner, a chmnber having a tangential air-inleL-an uil supply, an oil distributing plate near the bottem of the chamber. and baille plates am'anged in a spacedmair opposite the air inlet and leading downwardly to deflect the fuel mixture toward the center of the chamber. 7

2. In a liquid fuel bin'ner, a chamber having a tangentieLair-inlet, an. oil supply, an

oil distributigg plate near the bottom of the chzunber, and bafile plates arranged 0ppusite, the air inlet and inclined from to? m buttumin the direction of the movemem ml, the air current. and curved in ClOSS-wtl'flltill) Inward the air-inlet.

3. In a. liquid fuel burner, a chan'ilaer hering.a tangential air-inlet an nil supply, a. 25

perforated oil Clistrilmting plate at the bet tom of the chmnber, an igniting device under-the plate, and bafie plates mnefrueturl to deflect the air toward the distributing plate and the fuel mixture ixnv-rnd the center of the chamber.
